Product Introduction

The titanium grade 7 weld neck flange is a premium component designed for piping systems that face extreme corrosive environments. Made from ASTM B381 Grade 7 titanium, these flanges combine the strength of titanium with enhanced corrosion resistance due to the addition of 0.15% palladium. This makes them exceptionally resistant to crevice corrosion and reducing acids, outperforming even stainless steel in harsh conditions.
